Description

Technical Field

[0001] This application relates to the field of printing press equipment technology, and in particular to a printing press table support beam. Background Technology

[0002] A screen printing machine is a device that uses the principle of cutting out the text and image areas on a screen to print. Its core function is to accurately print text, patterns and logos on the surface of various materials such as fabric, metal, plastic film, and paper. It has a wide range of adaptability and is especially good at handling substrates that require high adhesion or special textures.

[0003] In related technologies, traditional screen printing machines typically use a configuration of one print head corresponding to three table support beams. For example, with 10 print heads on each side, three additional table beams are needed at each end, resulting in a total of 66 table support beams installed on the machine. However, when printing shoe materials, due to different process requirements, a configuration of one print head corresponding to six table support beams is used. For example, with 10 print heads on each side, six additional table beams are needed at each end, leading to a surge in the number of table support beams, with the total number of table support beams reaching as high as 132.

[0004] The existing platform support beams have the following problems: they are made of thick and long strips, and the weight of a single platform support beam is large. When multiple beams are stacked, the weight of the whole machine is significantly increased, which leads to problems such as excessive operating inertia, increased energy consumption, and accelerated mechanical wear. Summary of the Invention

[0005] To reduce the overall weight of the machine, this application provides a printing press table support beam.

[0006] The technical solution for a printing press table support beam provided in this application is as follows:

[0007] A printing press table support beam includes: a top plate, a table frame, and a bottom plate, wherein the top plate, the bottom plate, and the table frame are assembled to form a hollow, flat, rectangular parallelepiped-like structure.

[0008] By adopting the above solution, redundant materials are reduced. The hollow and flat cuboid structure effectively reduces its own weight while ensuring load capacity, thereby reducing the overall weight of the machine and reducing the occurrence of problems such as high operating inertia, high energy consumption, and accelerated mechanical wear caused by excessive weight.

[0009] Preferably, the top of the plate includes a recessed surface and two raised surfaces, which are arranged sequentially along the width direction and have a structure that is low in the middle and high on both sides.

[0010] By adopting the above solution, the table that supports the printing press can be made to rise and sink, forming edge support on the rising and sinking surfaces, effectively dispersing stress.

[0011] Preferably, the heights of the two rising surfaces are the same.

[0012] By adopting the above scheme, the printing platen is subjected to symmetrical bending moment, reducing deformation and maintaining stability during the printing press operation, thereby reducing the offset of the printed material on the printing platen and indirectly improving printing accuracy.

[0013] Preferably, the front end of the platform frame is set with an angled edge.

[0014] By adopting the above scheme, the inclined side setting can transform the concentrated load generated by printing pressure into an oblique component force, allowing the stress to diffuse along the diagonal of the frame, reducing fatigue cracking caused by stress concentration at right angles, and improving the durability of the structure.

[0015] Preferably, the hollow portion of the platform frame is provided with a plurality of reinforcing ribs, all of which are arranged in a V-shape, and the intersection and opening of the reinforcing ribs are respectively connected to the bottom and top of the platform.

[0016] By adopting the above scheme, the cross-layout of reinforcing ribs improves structural stiffness and effectively reduces bending deformation. While achieving lightweight design, it also reduces printing pressure through geometric self-stabilizing characteristics.

[0017] Preferably, the upper and lower surfaces of the bottom plate are thickened in both directions along the extension direction of the reinforcing rib.

[0018] By adopting the above solution, the local compressive strength is improved, and the installation of fasteners is facilitated.

[0019] Preferably, the connection between the platform frame and the bottom of the platform is provided with rounded corners.

[0020] By adopting the above solution, the stress distribution at the connection point is smoothly transitioned, which effectively reduces peak stress compared to a right-angle structure, reduces the generation of fatigue cracks, and extends service life.

[0021] Preferably, the bottom of the plate has a plurality of concave surfaces corresponding to the mounting surface on the printing press, and each of the plurality of concave surfaces is adapted to an external mounting component.

[0022] By adopting the above solution, the installation accuracy and ease of disassembly / reassembly of external mounting components have been improved.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Reduce redundant materials. The hollow and flat cuboid structure reduces the weight while ensuring load capacity, thereby reducing the overall weight of the machine and reducing the occurrence of large operating inertia, high energy consumption, and accelerated mechanical wear caused by excessive weight.

[0025] 2. Improved the load-bearing capacity and vibration resistance of the device;

[0026] 3. Improved the convenience and operational accuracy of the device. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a printing press table support beam. (Refer to...) Figure 1-2 A printing press table support beam includes a top plate 1, a table frame 3, and a bottom plate 2. The top plate 1, the bottom plate 2, and the table frame 3 are formed by extrusion molding using a mold to create a flat, hollow cuboid-like structure.

[0034] Correspondingly, this structural design achieves a balance between lightweight and high load capacity through optimized material distribution. While maintaining load-bearing capacity, it effectively reduces the structural weight and minimizes the impact of excessive inertia on the operation of the printing press. This reduces motion loss of the equipment under high-speed operation, extends the life of the machine, and is suitable for precision printing equipment that requires frequent start-stop.

[0035] Specifically, in this embodiment, the hollow part of the platform frame 3 is provided with three reinforcing ribs 31. All three reinforcing ribs 31 are arranged in a V-shape, and the intersection and opening of the reinforcing ribs 31 are connected to the bottom 2 and the top 1 of the platform, respectively.

[0036] Therefore, the stiffeners 31, through their cross-layout, form a three-dimensional force flow path with the bottom plate 2 and the bottom plate 2, which improves the overall structure and connection stiffness and effectively reduces bending deformation.

[0037] Furthermore, the V-shaped angle of the reinforcing rib 31 can reflect and offset part of the printing impact, and together with the hollow cavity, it dissipates energy and reduces the vibration amplitude. While achieving a lightweight design, the reinforcing rib 31 reduces the printing pressure through its geometric self-stabilizing characteristics, making it suitable for dynamic load conditions of printing presses.

[0038] Meanwhile, the upper and lower surfaces of the bottom plate 2 are bidirectionally thickened along the extension direction of the reinforcing rib 31 to form a thickened area 311. The thickened area 311 and the V-shaped reinforcing rib 31 form a continuous force transmission channel, so that the printing pressure is efficiently diffused to the plate frame 3 along the rib direction, improving the local compressive strength and reducing the occurrence of plastic deformation caused by stress concentration in the thin plate area.

[0039] Furthermore, the thickened area 311 reduces structural abrupt changes, makes the stress distribution more uniform, and facilitates the deep screwing of fasteners, so as to provide better fixation and support for the device.

[0040] On the other hand, the top of the plate 1 includes a recessed surface and two raised surfaces 12. The raised surfaces 12 and the recessed surface are arranged sequentially along the width direction, presenting a structure that is low in the middle and high on both sides.

[0041] Therefore, the rising surface 12, as a continuous support beam structure, disperses the printing pressure downward to the table frame 3, effectively improving the bending stiffness compared to the flat plate structure. The rising surface 12 forms edge support for the sinking surface, reducing the occurrence of large-area deformation of the sinking surface under stress and improving the load-bearing effect on the printing press table.

[0042] Specifically, in this embodiment, the two lifting surfaces 12 are kept at the same height after being processed by CNC milling cutter. The printing pressure is evenly transmitted to the two lifting surfaces 12 through the table. If one lifting surface 12 is too low, the vibration energy will be concentrated on the weak side, thereby causing abnormal wear of one lifting surface 12.

[0043] Correspondingly, the printing press table must be strictly parallel to the lifting surface 12, and the height tolerance of the lifting surface 12 must be precisely controlled to reduce the occurrence of uneven ink color, dot deformation, or periodic ghosting in the printing press.

[0044] Therefore, when the double lifting surfaces 12 are at the same height, they form a closed rigid loop, which can synergistically reduce the impact vibration generated during the operation of the printing press and keep the printing plate stable during the printing press operation, reduce the offset of the printed material on the printing plate, and thus indirectly improve the printing accuracy.

[0045] On the other hand, the front end of the table frame 3 is set with an inclined edge, which can convert the concentrated load generated by printing pressure into an oblique component force, so that the stress diffuses along the diagonal of the frame, reducing fatigue cracking caused by stress concentration at right angles and improving the durability of the structure.

[0046] Furthermore, the oblique boundary surface can change the transmission path of vibration waves and dissipate energy through refraction, thereby reducing the resonance amplitude caused by printing impact.

[0047] In addition, the connection between the table frame 3 and the bottom plate 2 is provided with a rounded corner 32, which makes the stress distribution at the connection smooth and transitions smoothly. Compared with the right angle structure, it effectively reduces the peak stress, reduces the generation of fatigue cracks, and extends the service life. At the same time, the rounded interface of the rounded corner 32 changes the vibration transmission direction and reduces the transmission of some resonance energy, which is suitable for the impact conditions of printing presses.

[0048] On the other hand, refer to Figure 3-4 In this embodiment, the bottom plate 2 is provided with ten concave surfaces 21 corresponding to the mounting surface on the printing press. All ten concave surfaces 21 are adapted to external mounting components to improve the installation accuracy and ease of disassembly of external mounting components such as linear bearings or fixed fulcrums.

[0049] The implementation principle of a printing press table support beam in this application embodiment is as follows: the device adopts a hollow and flat cuboid structure, which effectively reduces its own weight while ensuring load capacity, thereby reducing the overall weight of the machine and reducing the occurrence of large operating inertia, high energy consumption, and accelerated mechanical wear caused by excessive weight of the machine.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
